They are referred to as radio or wireless mics but are actually a case in which the original audio cable was replaced by a frequency transmitter technique. Radio mics are commonly used in transmitting audio by radio waves such as AM, FM, VHF, UHF or any other digital format.
The better ones operate from numerous frequencies that they use for transmission. That is why they hardly ever experience any interference by other electrical transmitters that are within the same frequency. They can enable the use of many microphones at the same time.
The very first type of radio microphones started as compander microphone development way back in 1976 and was used by Nady Systems. They were given recognition in 1996 and given an Emmy Award due to their technical input in the technological sphere.
These mics have many advantages because it enables the user to hold to some health and safety standards. They can now work without exposing themselves to too much risk due to what used to be the trailing cables of the microphones.
Then there is the advantage of easy movement because the wearer does not have to use any cables trailing the microphone. It used to be the case that the cables actually had some strain or stress because of the way they were tagged and pulled all the time. This used to cause them easy damage.
It might look like the advantages of the wireless mics far outweigh the disadvantages but wait a minute. What about the fact that the two way batteries are now not very long-lasting and they use much power?
Another disadvantage is the fact that the signals are normally hampered by the distance. They will require very strong and expensive batteries if you want to receive strong signals at a further distance. Interference is also caused easily by some electrical appliances that are within the same range.
It requires that one limits the number of radio microphones that can be used simultaneously in one given range.
